Purpose. Determination of the conditions for disappearance a section intermittent flow and its effect on strain hardening low-carbon steel.
 Actuality. The use low carbon steels with stamping has significant limitation. Based this, issues ferrite grain size occurrence are relevant determining optimal structural state intended deep drawing.
 Research methods. structure samples was stud...

We consider a fluid model including viscoelastic and viscoplastic effects. The state is given by the velocity an internal stress tensor that transported along flow with Zaremba-Jaumann derivative. Moreover, obeys nonlinear nonsmooth dissipation law as well diffusion. prove existence of global-in-time weak solutions satisfying energy inequality under general Dirichlet conditions for field Neuman...

This study tested two models of family economic problems and adolescent psychological adjustment. Using adolescents’ survey data and information regarding school lunch program enrollment, the associations among family SES, perceived economic strain, family conflict, and coping responses were examined in a sample of 364 adolescents from rural New England. Two theoretical models were tested using...

We used computer simulations to study spontaneous strain localization in granular materials, as a result of symmetry breaking non-homogeneous deformations. Axisymmetric triaxial shear tests were simulated by means of standard three-dimensional Distinct Element Method (DEM) with spherical grains. Carefully prepared dense specimens were compressed between two platens and, in order to mimic the ex...

In the present research, the relationship between the strain increment and Lode parameter was obtained by using Lode parameter and Levy-Mises equation. The quantitative relation between different strain increments was presented and the relationship between plastic deformation types and Lode parameter was demonstrated. The relations between plastic deformation types and stress states were reveal...

(Received: September 16, 1952) In our previous report (1), it was pointed out that the amount of free amino acids in the bacterial cell of sulfathiazol-resistant dysentery strain not only differed from that of sensitive one, but also varied depending upon the presence or absence of sulfathiazol in the culture medium. Attempts have been made to see if there is the similar relation in case of str...

The activities of some enzymes belonging to the Leloir pathway, phosphoglucomutase, UDP-glucose pyrophosphorylase, UDP-galactose 4-epimerase and galactose 1-P uridyl transferase, were studied in a wild ropy, a non-ropy and an overproducing mutant ropy strain of Streptococcus thermophilus. These activities were assayed over successive culture transfers along with exocellular polysaccharide (EPS)...
